Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537676, here are decompositions:

67 + 31537609 = 31537676
73 + 31537603 = 31537676
103 + 31537573 = 31537676
199 + 31537477 = 31537676
337 + 31537339 = 31537676
349 + 31537327 = 31537676
367 + 31537309 = 31537676
409 + 31537267 = 31537676

Showing the first eight; more decompositions exist.
